Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some
reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB
Concepts Guide for more information.

A zinc protein. Acts on primary or secondary alcohols or hemi-acetals with very broad specificity; however the enzyme oxidizes methanol much more poorly than ethanol. The animal, but not the yeast, enzyme acts also on cyclic secondary alcohols.
